1 INK-BO TL Be it knownthat I, JAMES L. MoWnon TER, a citizen of the United States, and resi dent of La Fayette, county of \ValkenState of Georgia, have invented certain new and useful Improvements in Ink-Bottles; of which the following is aspecification V This invention relates to ink stands or bottles and more particularly to an automatically self-righting inkbottle. One of theobj ects of the present invention is to improvethe construction of ink bottles.

and. to provide a simple and comparatively inexpensive ink bottle adapted when upset or knocked down to right itself instantly and amount of ink tending to flow from the A further object of the invention is to provide an ink bottle having means therein Gm p invention will pable' of protecting the point or the .penand of preventing the same'fromidippingup too much ink-and ofinsuring a uniform supply of ink to the pen-until practicallytheentire v contents of the bottle is consumed.

- Another objectis to provide an improvedfloat tube which will protect. the ink in the bottle .from exposure v to the atmosphere thereby'preventing evaporation of the ink. Other obj ects-a-ndthe novel features of the drawing, in which,

.ceptalejlO presents a smooth rounded ex.- 4 terior surface and cooperates with the weight 14in causing the ink instantly when upset or weight which is designed to. beconstructed bottle to i right itself knocked down. The

of lead or any-other suitable material may be secured in the recess 13 in any suitable manner, such as'by screw threads oryby being molded or cemented in the recess. The lower face of the weight is flush with the baseof the ink bottle and the entire bottomof the securing therebottle is covered bygluing or thin pad.'1'5.of

to :in any suitable manner a soft rubber, felt or similari'materialto prevent nolse and to afford-frictional contact on sloping surfaces, thereby preventing'slidmg. "The pad will alsoenable' the ink bottle ,to be placed on and moved over polished sur faces, without scratching or otherwise marring the same.

The tapered .upper portion-or neck of the bottle has an inwardly extendinghorizontal annular top .or flange 16 having an upwardly projecting portion 16 providing an exterior recess 17 forthe reception of a mouth piece18 having a ccncaveiy curved outer faceforming a continuation ofand arranged flush with theslightlycurved outer The mouth.

rubber or similar'material is provided at the lower edge with an interior annular recess 19 having screw'gthreads thereon to engage corresponding threads in the exterior recess 17 on the flange 16. 'bottle being thus of thinner material than the bottom and narrowed inwardly toward" the neck,

The upper part ofthe reduces the amount of wall in this part of the bottle. In addition to the reduc-; tion of weight M the upper parto-f the body of the bottle, the mouth piece constructed of lighter material,- is of much less weight than glass and the like. Thesefeatures assist in providing a bottle which will readily; right itself. Furthermore the body portion of the bottle is so designed and proportioned .with' reference to in case the bottle. is tipped over and rests for a moment on its side, or on'its side, and'the edge of-the mouth piece; and the ink therein flows towardthe upper end which in such anvevcnt would beht 'of'the mouth piecefneck portion afi'ordedpby thus necking in screwed ofl' of the bottle.

tomaintain the bottle in an" upright position, i

The mouth piece is readily detachable to afford access tothe interior of the bottle and removably secures therein a stationary depending cylindrical casing 20,which fits snugly into the neck of the bottle at'the top or flange 16 and is provided at. its upper edge with an outwardly extending horizon tal flange 21'; The flange 21. is held between J the flange 16 'andthe mouth piece 18 or the flange 21 maybe omitted and the upper end of the casing threaded as indicated at 201 in Fig. 8 to engage threads 181 on the mouth piece 18,0fthe bottle. As shown in Fig. 9, the flange 2l'm'ay beprovided with exterior screw threads 211 of the samersize;

i 4 The upper portion of the mouth piece has an interior taper or flare 22 and is provided at the bottomthereof with a depending overhanging guard flange 23 adapted should the bottle upset to catch any small amount of ink which might tend to flow from the bottle. The inner face of the guard flange 23 is inclined and arranged at an angle to the vertical inner face of. the lower portion of the mouthv piece to'form an annular groove or gutter 24 to catch any outflowing ink; v

The depending tube or casing 20 which is also preferably constructed of hard rubber receives and forms a guide for a floatingink' supply casing 25 of approximately inverted conical shape constructed of hard rubber or other suitable material. An enlarged vertical cross sectionalview of the said casing 25 is shown in Fig. '3. The casing-25 is pro- "vided at the upper edge thereof with a depending annularflange 26 arranged verti- Cally-and adapted to snugly fit the interior of the depending 'tube or casing 20, being -guided by the latter. Both the outer surface of the flange 26 and the inner surface of the dependingtube 20 are very smooth to permit the conical casing 25 to slide easily up and down. The upper portion of the floating cone or casing 25 is flared and a corkring 27 is arranged in the v-annular spaceor recess between the flange 26 and the flaring portion thereof to render the casing 25 buoyant so that the casing will float on the surface of theink and fall as the ink is consumed. Any other suitable material may be employed for accomplish:

ing this result, such as providing a hollow portion or chamber around the cone.

The lower end of the cone is truncated, however, the same may be cylindrical as shown in Fig. 6 and slightly rounded at the bottom to permit the same to go to the bot-- tom of the sump in the bottom of the bottle. It will be seen that the inner surface of the bottle gradually slopes tothe bottom toward thesum p ,to allow all of the ink to flow into the sump. The lower end is provided with a horizontal bottom '28 having a central opening 29 therein toadmit ink into the lowerportion of the casing. The lower portion of the cone or casing forms 'a float or valve chamber 30-having at the top-an inwardly extending flange adapted to'forln a stop to limit the upward movement of a degressible float orva'lve member 31'. The flange at the upper end of the valve chamber is provided at intervals with recesses '32 which leave intervening projections 33 ex-i gending inwardly over and engaging the oat.

The float which is ireferably made of cork to protect oravoid injuring the point of a .pen has its top. dished or hollowed out -as at 34 to form an ink cup and when a pen is inserted into the bottle the float is depressed and operates as a valve to close the bottom opening 29 and shuts off the flow of the ink into the float chamber 30. At the same time the recesses or openings 32 permit the ink in the float chamber 30 to flow over the float into'the dished out upper face pr. in k cup 34 and a uniform depth of ink is exposed to the pen so-that the latter will not fdip up too much ink. ..The float which is tapered downward is cut away at the sides below the top flange leaving suflicient space between the cone and the float for the ink which "presses the float upward against the flange .at the top of the float chamber. The

recessed upper-face 34 of the float reduces the weight of the latter and enables the pen to dip into the ink the desired depth without danger of the pen taking up to'o much inkand blotting the'paper. The depth to.

which the pen is allowed to go in the ink is regulated by the depthto which the'lower partof the cone is allowed-to go into the ink. The outer face of the flange 26 and the inner face of the tube or casing 20 have asmooth finish to enable the conical member 25 to move freely in the tube or casing 20 and at the same time will preventthe ink leaking over the top of the cone.

Fig. 4 is an enlarged sectional view of a modified form of the floating casing or cone. In this illustration the cone is made up of thelower hard rubber portion 35 provided at its upper end with screw threads 36 or'other attaching means by which it is connectedfto an annular ,lccnical member 37 of cork orhimilar floating material adapted to sliden v i thin the'tube 20.
